IMPROVEMENT IN PLANING-MACHINES.

Specification forming part of Letters Patent No. 56,254, dated July l0, 1866.`

To all whom it may concern:

Be it known that I, DANIEL NILEs, of Fly Creek, in the county of Otsego, in the State of New York, have invented a new and use ful Machine for Planing Sawed Shingles; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a complete elevation of the machine when ready for use; and Fig. 2 is asimilar exhibition, with the bed a raised in order to show the cutter-head b and some other parts of the machine more plainly.

In its general form and construction the machine resembles an ordinary planer, but is peculiar in certain of its parts, in order to conform to the peculiar use for which it is designed-viz., the planing of a wedge-shaped article. It has a frame, c, and driving-shaft e, with pulley f, Fig. 2, the latter to receive a belt from the motive power, and the large pulley g, which, through the belt 7L, turns the cutter-head b. All this, with the exception of the location and 'arrangement of' the bed and bed-frame a, is similar to corresponding parts of the ordinary planer; but instead of the bed-frame being beneath the cutter-head it is above it, and the shingles, instead of being fed in beneath the cutter-head, are carried over it, and the cutters plane them on the under side.

The cutter-liead b is fixed and immovable, except its rotatory motion; but the bed a, with its frame, is movable and adjustable. It is hinged to the main frame at one end, as seen at t' t', and may be lifted up, as shown in Fig. 2, for convenience of repairs and other purposes. It is adjustable at the opposite end by means of the screw-bolt 7c and the setscrews L l.

In order to let the frame a down to its place the nut m is removed and the bolt lc passes through the orifice n in the bar o. The nut m is then returned to its place on the bolt underneath the bar o. The feather-springs pp rest on the bar o, and the washer r, preceding the nut m when screwed up, acts against the`under side of the fixed bar o.

By this means it is evident that the bedframe a, on which the shingles are fed to the cutters, may be raised or lowered, and the depth of the cut thus regulated. When properly adjusted its position is secured firmly by means of the set-screws l Z, which pass through the frame and act against the feather-springs p p, the latter resting on the solid bar o of the frame, as aforesaid. Thus, as the shingle is fed to the cutter-knives on the bed a, Fig. l, the depth of the cut in planing the under surface is regulated at one end of the bedfralne, as described, the other end being hinged to the main frame, as described.

The shingles are introduced by hand, the thin end foremost, on the bed a, and are carried through by the iiuted feed-rollers s s, the cutters b acting on the under side, as described. These feed-rollers act pliantly on the upper surface, and accommodate themselves to the varied thicknesses of the shingles by reason of the springs t t t t. These springs being screwed down to the frameat one end, as seen at u, and at the opposite end pressing upon blocks t, let down loosely in gains cutinto the frame, so that they rest on the axles of the rollers, and thus the under surface of the shingle, resting on the fixed bed a, is always the same in its presentation to the cutter-knives, and the feed-rollers acting on the inclined plane of the upper surface conform to the varied thicknesses of the shingles by reason of the pliancy of these elastic rollers.

The feed-rollers are in the ordinary way propelled by a belt on the opposite side of the machine, extending from the opposite end of the driving-shaft e to the pulley w, Fig. l, on the shaft of which is the center pinion, x. This pinion, connecting with similar pinions y y on the respective shafts of the feed-rollers on either side, turns the feed-rollers in the proper direction. Thus the shingle is planed uniformly from end to end, preserving the taper of the shingle perfectly.

Having thus described the construction and operation of rny machine, I claim as my invention and desire to secure by Letters Patent- Planing tapering shingles on one side by means of the revolving cutters in fixed bearings, and feeding the shingles to such cutters upon a hinged adjustable frame With feedrollers that are in yielding bearings and arranged to operate substantially as described, and for the purpose set forth.

DANIEL NILES.
